1) Is 2.1 better for performance than my current 2.0.1? I would like some of the new features, but since I have MANY apps hogging my memory I would not want to sacrifice speed just to get multitouch, etc.
2) I am running 2.0.1 with Helix, rooted, renamed stock launcher to "launcher.bak" as I was told this would slightly speed up the phone. I once tried to install 2.1 and my phone froze with the exclamation point graphic! I rebooted it and it came back up fine, Helix was happy, but it was still running 2.0.1. What do you think had gone wrong with the install?
